A weak ignition coil may contribute to hard starting, rough idle, hesitation, weak acceleration, reduced fuel economy, misfire symptoms, or a check engine light. Similar symptoms can also come from worn spark plugs, wiring problems, fuel delivery faults, intake leaks, sensors, or engine mechanical condition.
Install on a cool engine. Inspect the spark plugs, coil boots, wiring connectors, and mounting area before installation. BDFHYK ignition coils are OE-style aftermarket replacement parts, not factory-branded Infiniti or Nissan parts.
